“Derek has really taken to the offense well,” Knapp said. “This week, in the last two days, we’ve had very good practices with those two young guys, but they’re still young guys, and I hate to put a burden on a rookie receiver if we don’t have to. You’ll probably see a rotation of all four of them playing of some sort.

“He’ll be able to handle releases off press-coverages from Champ Bailey a little more than a rookie because he’s handled that in the past with his experiences.”

Hagan has 8 catches for 84 yards on the season. Streater has 8 for 68 and a Week 1 touchdown.

Rookie Juron Criner is the other young receiver that Knapp is referring to. He didn’t catch any balls the first week before being inactive the last two weeks with an ankle injury and the return of Denarius Moore from his hamstring injury. Now he will be active against the Broncos with Heyward-Bey out.

Here’s Knapp on Criner:

“Like Rod has been, there’s been some good weeks, and some learning weeks,” Knapp said. “They both have made progress and that’s a pleasing sign to see. With Juron, it kind of set him back, that injury. A young guy can’t afford to miss reps. With the injury he had he’s fully recovered now from the [ankle]and he’s made progress this week.”
